Solid-state nanopores as a versatile alternative to biological nanopores have grown tremendously over the last two decades. They exhibit unique characteristics including mechanical robustness, thermal and chemical stability, easy modifications and so on. Moreover, the pore size of a solid-state nanopore could be accurately controlled from sub-nanometers to hundreds of nanometers based on the experimental requirements, presenting better adaptability than biological nanopores. Two-dimensional (2D) materials with single layer thicknesses and highly ordered structures have great potential as solid-state nanopores. In this perspective, we introduced three kinds of substrate-supported 2D material solid-state nanopores, including graphene, MoS₂ and MOF nanosheets, which exhibited big advantages compared to traditional solid-state nanopores and other biological counterparts. Besides, we suggested the fabrication and modulation of 2D material solid-state nanopores. We also discussed the applications of 2D materials as solid-state nanopores for ion transportation, DNA sequencing and biomolecule detection.

二维材料作为化学传感的固态纳米孔

固态纳米孔作为生物纳米孔的多功能替代品在过去二十年中得到了巨大的发展。它们表现出独特的特性，包括机械坚固性、热稳定性和化学稳定性、易于修改等。而且，固态纳米孔的孔径可以根据实验要求从亚纳米到数百纳米精确控制，比生物纳米孔具有更好的适应性。具有单层厚度和高度有序结构的二维（2D）材料作为固态纳米孔具有巨大的潜力。从这个角度来看，我们介绍了三种基底支撑的二维材料固态纳米孔，包括石墨烯、MoS ₂和MOF纳米片，与传统固态纳米孔和其他生物同类材料相比，它们表现出巨大的优势。此外，我们还提出了二维材料固态纳米孔的制造和调制。我们还讨论了二维材料作为固态纳米孔在离子传输、DNA 测序和生物分子检测中的应用。
